PPL Event Request for RE-INVITE Message
Overview
This section includes a description of the feature, call flows, and the PPL changes to support the feature.
Description
This feature allows the CSP to support the RE-INVITE message for a Call Agent Mode call in bearer-free mode using PPL Event Request (0x0024). This PPL Event Request generates a Re-INVITE regardless of the call direction: incoming or outgoing.
This PPL Event Request will work only if the call is in bearer-free mode or else it will NACK with a value 0x130C (Call is not in bearer-free mode.)
Call Flows
Third Party Connected to Called Party
The call flow below shows a scenario where the initial conversation between SIP endpoints (A/B) is put on hold and a third party (C) is connected to the called party of the initial conversation (B). The call flow begins below and continues on the next page.

PPL Changes
The following PPL change supports this feature.
PPL Event Request to Generate RE-INVITE message
PPL Event Request (0x0024)
The PPL Event Request (0x0024) is used to generate a RE-INVITE message to the SIP endpoint connected to the channel indicated in the channel AIB.
This PPL Event Request will work only if the call is in bearer-free mode or else it will NACK with a value 0x130C (Call is not in bearer-free mode.)
The PPL Event Request is added to the SIP UA (0x00A7) component. Refer to PPL Information: SIP UA 0x00A7
When the PPL Event Request generates a RE-INVITE message, the 200 OK SIP message received from the other end having the SDP information will be reported to the host application using the PPL Event Indication (0x0020) by the SIP UA component.
The data in the PPL Event Indication could be used within the subsequent Connect with Data (0x0005) message. The PPL Event Request is ACKED if the data is valid.
Important! The PPL Event Request should contain a Media Remote End Point Info (0x2A00) TLV.
